working principle

A nitrogen generator is based on the principle of pressure swing adsorption, using carbon molecular sieves as adsorbents to produce nitrogen from air at rated pressure. After purification and drying under compression pressure, pressure adsorption and depressurization desorption are carried out in adsorption. Due to aerodynamic effects, the diffusion rate of oxygen in the micropores of carbon molecular sieves is much higher than that of nitrogen. Oxygen is preferentially adsorbed by carbon molecular sieves, while nitrogen is enriched in the gas phase, forming finished nitrogen gas. Afterwards, after decompression to atmospheric pressure, the adsorbent desorbs impurities such as oxygen adsorbed, achieving regeneration. Generally, two adsorption towers are set up in the system, one tower adsorbs and produces nitrogen, and the other tower desorbs and regenerates. The opening and closing of the pneumatic valve is controlled by a PLC program controller to alternate between the two towers, in order to achieve continuous production of high-quality nitrogen gas.

Industry Applications
One SMT Industry Applications
Surface Mount Technology (SMT) for electronic circuits, also known as surface mount or surface mount technology. It is a circuit assembly technology that installs surface mount components (SMC/SMD) without pins or short leads on the surface of a printed circuit board (PCB) or other substrate, and assembles them by soldering or immersion welding. Nitrogen filled reflow soldering and wave soldering can effectively suppress the oxidation of solder, improve the wetting properties of solder joints, accelerate the wetting speed, reduce the generation of solder balls, avoid bridging, reduce welding defects, and achieve better welding quality. Use nitrogen with a purity greater than 99.99.99% or 99.9% 99.9%
